The graph of the function f(x) is shown below. It consists of a semicircle and two straight line segments. 150 + -3 -2 y 3 2 -1 1 2 (b) Which of the following numbers is the smallest: ƒ' (−3.95), ƒ' (−1.5), ƒ' (−0.05), ƒ' (1), ƒ' (3.05)? 3 5 X

The U.S. population can be modeled by the function y=165.6x¹.345, where y is in thousands and x is the number of years after 1800. (a) What was the population in 1970, according to this model? (b) is the graph of this function concave up or concave down? What does this mean? (c) Use numerical or graphical methods to find when the model estimates the population was 94,150,000. (a) According to the model, the population in 1970 was thousands. (Round to the nearest integer as needed.)

What is the function.  Is it 30 - (1/1000)x

4. Find the slope of f(x) = hundredth. -3x-1 at (2,-1.65). Use a graphing utility and round to the nearest 3√x
